The Page Select (FPS) register
pages to be erased or programmed. Each Flash Page contains 512 bytes of Flash memory.
During a Page Erase operation, all Flash memory locations with the 7 most significant bits
of the address given by the PAGE field are erased to
The Page Select register shares its Register File address with the Flash Sector Protect Reg-
ister. The Page Select register cannot be accessed when the Flash Sector Protect register is
enabled.
INFO_EN—Information Area Enable
0 = Information Area is not selected.
1 = Information Area is selected. The Information area is mapped into the Flash Memory
address space at addresses FE00H through FFFFH.
